Eu encontrei esta solução alternativa aqui , eu tentei e funcionou para mim:
Edit the file:
/etc/pulse/default.pa
and comment out (with an # at the beginning of the line) the following line:
#load-module module-bluetooth-discover
now edit the file:
/usr/bin/start-pulseaudio-x11
and after the lines:
if [ x”$SESSION_MANAGER” != x ] ; then /usr/bin/pactl load-module module-x11-xsmp “display=$DISPLAY session_manager=$SESSION_MANAGER” > /dev/null fi
add the following line:
/usr/bin/pactl load-module module-bluetooth-discover
